Sequence Models - Week3 - Trigger Word Detection

[datasc-masa]

Hi and thanks for your repository...
It seems that there is a problem in "Trigger_word_detection_v2a.ipynb" file...
After "create_training_example" method, its test asserts norm of Spectrogram and it should be close to 39745552.52075 and there is a problem in this assertion because it failed and throw an exception. a notable issue is that when we execute this test, the "create_training_example" function add two "activates" and also two "negatives" (based on a copy of your presented function) but in your file based on the test output there is three added audios on background. maybe this is the reason of this problem in you file. please check and debug if you find the problem.

best regards...
